Would love to have a "Dismiss” option for pending responses (manager-side cleanup) on perm class openings

Current issue: when an instructor responds “Yes,” it can clutter the manager view as “Pending,” even if the manager already knows they won’t select that instructor.

Request: Add a Dismiss action so managers can remove an instructor’s “Yes” from the pending view and return the opening back to Open (without changing what the instructor submitted).

Follow-on requests tied to Dismiss:

-Audit trail/activity history (who dismissed, when)

-Optional reason/comment when dismissing

-Optional notification/email to the instructor if they’re dismissed (and/or not selected)
